From pink lightning and northern lights to stars far far away, here's your daily dose of nighttime sky-candy.
It used to be that anywhere you lived you likely had a pretty good view of the mysterious splendors the sky has to offer. But modern life comes with a lot of artificial light that, with the flick of a switch, puts the kibosh on enjoying the nighttime sky. Which is a profound loss – we’ve been gazing at the sky since the beginning of civilization; few things are as inspiring. A recent study from the University of Vermont found that 99 percent of the world's skies are victim to some degree of light pollution ... two-thirds of Americans can't even see the Milky Way from their homes. (See more in We're losing the nighttime sky.)
Fortunately, it’s not all gloom and doom. While light pollution does further harm than just depriving humans of pondering the heavens, it is reversible and there are a number of organizations addressing the problem.
But in the meantime, if you suffer from Nighttime Sky Deficit Disorder (NSDD) (and yes, I just made that up) we’ve got the cure right here.
First up, the aurora borealis above, showing off its fancy magic in a photo taken by Swedish flickr user, oskar karlin. Sweet sweet sky!
